Over the last 5 decades, many acoustic measures have been created to measure roughness and breathiness. The aim of this study is to present a meta-analysis of correlation coefficients (r) between auditory-perceptual judgment of roughness and breathiness and various acoustic measures in both sustained vowels and continuous speech.
Scientific literature reporting perceptual-acoustic correlations on roughness and breathiness were sought in 28 databases. Weighted average correlation coefficients (rw) were calculated when multiple r-values were available for a specific acoustic marker. An rw ≥ .60 was the threshold for an acoustic measure to be considered acceptable.
From 103 studies of roughness and 107 studies of breathiness that were investigated, only 33 studies and 34 studies, respectively, met the inclusion criteria of the meta-analysis on sustained vowels. Eighty-six acoustic measures were identified for roughness and 85 acoustic measures for breathiness on sustained vowels, in which 43 and 39 measures, respectively, yielded multiple r-values. Finally, only 14 measures for roughness and 12 measures for breathiness produced rw ≥ .60. On continuous speech, 4 measures for roughness and 21 measures for breathiness were identified, yielding 3 and 6 measures, respectively, with multiple r-values in which only 1 and 2, respectively, had rw ≥ .60.
This meta-analysis showed that only a few acoustic parameters were determined as the best estimators for roughness and breathiness.
在过去50年里，人们创造了许多声学测量方法来测量粗糙度和气息声。本研究的目的是对持续元音和连续语音中粗糙度和气息声的听觉感知判断与各种声学测量之间的相关系数（r）进行荟萃分析。
在28个数据库中搜索报告粗糙度和气息声感知-声学相关性的科学文献。当一个特定声学标记有多个r值时，计算加权平均相关系数（rw）。rw≥0.60是一种声学测量被认为可接受的阈值。
在调查的103项粗糙度研究和107项气息声研究中，分别只有33项研究和34项研究符合持续元音荟萃分析的纳入标准。在持续元音上，确定了86种粗糙度声学测量方法和85种气息声声学测量方法，其中分别有43种和39种测量方法产生了多个r值。最后，只有14种粗糙度测量方法和12种气息声测量方法的rw≥0.60。在连续语音中，确定了4种粗糙度测量方法和21种气息声测量方法，分别产生了3种和6种有多个r值的测量方法，其中分别只有1种和2种测量方法的rw≥0.60。
这项荟萃分析表明，只有少数声学参数被确定为粗糙度和气息声的最佳估计指标。
